Immutable branch between MFD and HWMON due for the v4.18 merge window

The hard-coded 10ms delay in mmc_power_up came from
commit 79bccc5aefb4 ("mmc: increase power up delay"), which said "The TI
controller on Toshiba Tecra M5 needs more time to power up or the cards
will init incorrectly or not at all." But it's too engineering solution
for a special board but force all platforms to wait for that long time,
especially painful for mmc_power_up for eMMC when booting.
However, it's added since 2009, and we can't tell if other platforms
benefit from it. But in practise, the modern hardware are most likely to
have a stable power supply with 1ms after setting it for no matter PMIC
or discrete power. And more importnatly, most regulators implement the
callback of ->set_voltage_time_sel() for regulator core to wait for
specific period of time for the power supply to be stable, which means
once regulator_set_voltage_* return, the power should reach the the
minimum voltage that works for initialization. Of course, if there
are some other ways for host to power the card, we should allow them
to argue a suitable delay as well.
With this patch, we could assign the delay from firmware, or we could
assigne it via ->set_ios() callback from host drivers.

The b53 driver already defines and internally uses platform data to let the
glue drivers specify parameters such as the chip id. What we were missing was
a way to tell the core DSA layer about the ports and their type.
Place a dsa_chip_data structure at the beginning of b53_platform_data for
dsa_register_switch() to access it. This does not require modifications to
b53_common.c which will pass platform_data trough.

Now ->max_namelen() is only called to limit the filename length when
adding NUL padding, and only for real filenames -- not symlink targets.
It also didn't give the correct length for symlink targets anyway since
it forgot to subtract 'sizeof(struct fscrypt_symlink_data)'.
Thus, change ->max_namelen from a function to a simple 'unsigned int'
that gives the filesystem's maximum filename length.

The set of APIs we provide has a few holes for coarse times, e.g. we
provide ktime_get_coarse_boottime() and ktime_get_boottime_ts64(),
but not the combination of the two.
This adds four new functions:
ktime_get_coarse_boottime_ts64()
ktime_get_boottime_seconds()
ktime_get_coarse_clocktai_ts64()
ktime_get_clocktai_seconds()
to fill in some of the missing pieces. I have missed only the
ktime_get_boottime_seconds() accessor in a few occasions in
the past, but it seems better to just provide all four together,
as there is very little cost to having them.

I have run into a couple of drivers using current_kernel_time()
suffering from the y2038 problem, and they could be converted
to using ktime_t, but don't have interfaces that skip the nanosecond
calculation at the moment.
This introduces ktime_get_coarse_with_offset() as a simpler
variant of ktime_get_with_offset(), and adds wrappers for the
three time domains we support with the existing function.

At this point, we have converted most of the kernel to use timespec64
consistently in place of timespec, so it seems it's time to make
timespec64 the native structure and define timespec in terms of that
one on 64-bit architectures.
Starting with gcc-5, the compiler can completely optimize away the
timespec_to_timespec64 and timespec64_to_timespec functions on 64-bit
architectures. With older compilers, we introduce a couple of extra
copies of local variables, but those are easily avoided by using
the timespec64 based interfaces consistently, as we do in most of the
important code paths already.
The main upside of removing the hack is that printing the tv_sec
field of a timespec64 structure can now use the %lld format
string on all architectures without a cast to time64_t. Without
this patch, the field is a 'long' type and would have to be printed
using %ld on 64-bit architectures.

Many places in drivers/ file systems, error was handled in a common way
like below:
ret = (ret == -ENOMEM) ? VM_FAULT_OOM : VM_FAULT_SIGBUS;
vmf_error() will replace this and return vm_fault_t type err.
A lot of drivers and filesystems currently have a rather complex mapping
of errno-to-VM_FAULT code. We have been able to eliminate a lot of it
by just returning VM_FAULT codes directly from functions which are
called exclusively from the fault handling path.
Some functions can be called both from the fault handler and other
context which are expecting an errno, so they have to continue to return
an errno. Some users still need to choose different behaviour for
different errnos, but vmf_error() captures the essential error
translation that's common to all users, and those that need to handle
additional errors can handle them first.

When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.
This model allows to offload TC eswitch rules between VFs belonging
to different PFs (and hence have different eswitch affinity), it also
sets the some of the foundations needed for uplink LAG support.

When TCP receives an out-of-order packet, it immediately sends
a SACK packet, generating network load but also forcing the
receiver to send 1-MSS pathological packets, increasing its
RTX queue length/depth, and thus processing time.
Wifi networks suffer from this aggressive behavior, but generally
speaking, all these SACK packets add fuel to the fire when networks
are under congestion.
This patch adds a high resolution timer and tp->compressed_ack counter.
Instead of sending a SACK, we program this timer with a small delay,
based on RTT and capped to 1 ms :
delay = min ( 5 % of RTT, 1 ms)
If subsequent SACKs need to be sent while the timer has not yet
expired, we simply increment tp->compressed_ack.
When timer expires, a SACK is sent with the latest information.
Whenever an ACK is sent (if data is sent, or if in-order
data is received) timer is canceled.
Note that tcp_sack_new_ofo_skb() is able to force a SACK to be sent
if the sack blocks need to be shuffled, even if the timer has not
expired.
A new SNMP counter is added in the following patch.
Two other patches add sysctls to allow changing the 1,000,000 and 44
values that this commit hard-coded.

operation as function arguments as well as on iter_info struct.
The difference is that iter_info struct may contain marks that should

Instead of passing the inode_mark and vfsmount_mark arguments, add

An fsnotify_mark_connector is referencing a single type of object
(either inode or vfsmount). Instead of storing a type mask in
connector->flags, store a single type id in connector->type to
identify the type of object.
When a connector object is detached from the object, its type is set
to FSNOTIFY_OBJ_TYPE_DETACHED and this object is not going to be
reused.
The function fsnotify_clear_marks_by_group() is the only place where
type mask was used, so use type flags instead of type id to this
function.
This change is going to be more convenient when adding a new object
type (super block).

As part of aerdrv_core.c, these callbacks were built under CONFIG_PCIEAER.

The source e-switch owner allows a vport on one e-switch port be associated
with a rule defined on the second port e-switch.
The role of the source eswitch owner valid bit in the flow group is to
allow the firmware fail driver attempts to wild card the source eswitch
match field. If this bit is not set, the firmware ignores the source
eswitch owner field totally.

The destination e-switch owner allows a rule in namespace of one e-switch
owner to point to a vport that is natively associated with another
e-switch owner.

When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.
Under merged eswitch, both the matching on source vport and setting
destination vport can have a 2nd attribute which is the vhca id of the
eswitch owner.
For example:
esw0: {match: <src vport=1 owner=0> action: fwd to <dst vport=7, owner=1>}
is a flow set on eswitch0 matching on source vport=1 from his eswitch
and the action being fwd to dest vport=7 of eswitch1.

Kalle Valo says:
====================
wireless-drivers-next patches for 4.18
The first pull request for 4.18. As usual new features and bug fixes
but nothing really special.
I also merged wireless-drivers due to an iwlwifi patch dependency.
Major changes:
iwlwifi
* implement Traffic Condition Monitor and use it for scan, BT coex and
to detect when the AP doesn't support UAPSD properly
* some more work for the 22000 family of devices;
* introduce AMSDU rate control offload
qtnfmac
* DFS offload support
rsi
* roaming enhancements
* increase max supported aggregation subframes
* don't advertise 5 GHz support if the device doesn't support it
brcmfmac
* add support for BCM4366E chipset
* add support for bcm43364 wireless chipset
ath10k
* enable temperature reads for QCA6174 and QCA9377
* add firmware memory dump support for QCA9984
* continue adding WCN3990 support via SNOC bus

After the previous patch, for NOLOCK qdiscs, q->seqlock is
always held when the dequeue() is invoked, we can drop
any additional locking to protect such operation.

Call ACPI cache parsing routines from base cacheinfo code if ACPI
is enabled. Also stub out cache_setup_acpi and acpi_find_last_cache_level
so that individual architectures can enable ACPI topology parsing.

ACPI 6.2 adds a new table, which describes how processing units
are related to each other in tree like fashion. Caches are
also sprinkled throughout the tree and describe the properties
of the caches in relation to other caches and processing units.
Add the code to parse the cache hierarchy and report the total
number of levels of cache for a given core using
acpi_find_last_cache_level() as well as fill out the individual
cores cache information with cache_setup_acpi() once the
cpu_cacheinfo structure has been populated by the arch specific
code.
An additional patch later in the set adds the ability to report
peers in the topology using find_acpi_cpu_topology()
to report a unique ID for each processing unit at a given level
in the tree. These unique id's can then be used to match related
processing units which exist as threads, within a given
package, etc.
